The camera has 2 types of gain, including the analog gain and digital gain. The analog gain is
applied before the signal from the camera sensor is converted into digital values, while digital gain
is applied after the conversion.
When increasing the analog gain, the image noise will increase too, which will influence image
quality. If you want to increase image grayscale value, it is recommended to increase the camera’s
exposure time. If the exposure time reaches its upper limit, and at this point, you can increase
analog gain.
